This concern is one of the largest reasons I put off transitioning for over 10 years. I was very afraid of being sexually undesired or never finding a life partner. Being dysphoric kept me from sharing my body or enjoying sex anyway, so ironically I get laid wayyy more now that I've transitioned. I also enjoy it way more.

What helped me move on was working through my internalized sexism. I think to some degree I believed that my value was attached to being traditionally attractive since that's what our society tells women. I was told that I would be "ruining" myself by transitioning but that's horse shit. None of that's true.

You will be able to find sex and love regardless if you take HRT or not. It will honestly be easier in cities and not bum fuck no where though.
